Abstract: A dual-phase steel, a flat product and processes for the production thereof. The dual-phase steel having a strength of at least 950 MPa, good deformability, and good surface finish. It is possible, when a simple production process is used, for the flat product produced from this steel to be formed into a complexly formed component, such as part of a car body, either uncoated or provided with an anti-corrosion coating. The steel according to the invention has a structure comprising 20-70% martensite, up to 8% retained austenite and the remainder ferrite and/or bainite and has the following composition (in % by weight): C: 0.050-0.105%, Si: 0.20-0.60%, Mn: 2.10-2.80%, Cr: 0.20-0.80%, Ti: 0.02-0.10%, B: <0.0020%, Mo: <0.25%, Al: <0.10%, Cu: up to 0.20%, Ni: up to 0.10%, Ca: up to 0.005%, P: up to 0.2%, S: up to 0.01%, N: up to 0.012%, remainder iron and unavoidable impurities.

Abstract: A dual-phase steel, a flat product produced therefrom and a process for the production thereof. The dual-phase steel has, in addition to a strength of at least 950 MPa and good deformability, a surface finish which, when a simple production process is used, makes it possible for the flat product produced from this steel to be formed into a complexly formed component, such as a part of a car bodywork, in an uncoated state or in a state provided with an anti-corrosion coating. The steel according to the invention comprises 20-70% martensite, up to 8% retained austenite and the remainder ferrite and/or bainite and comprises (in % by weight): C: 0.10-0.20%, Si: 0.10-0.60%, Mn: 1.50-2.50%, Cr: 0.20-0.80%, Ti: 0.02-0.08%, B: <0.0020%, Mo: <0.25%, Al: <0.10%, P: ?0.2%, S: ?0.01%, N: ?0.012%, the remainder iron and unavoidable impurities.
